Semester 2

• Visit my website BEFORE you ask me what you missed in class.

• If the absence is excused…– A HW assignment is due by the next class.– A quiz must be made up before the next class.– A test will be made up on the Tuesday following

the test.• If the absence is unexcused…

1. Don’t ditch my class.2. You get a ZERO for the missing HW, quiz,

test!

• Time Issues– The weekly lab quiz will open Friday at 7:30 AM

and close on Monday at 3:00PM.– Moodle quizzes will not be excused or retaken

without SERIOUS extenuating circumstances• Vocabulary

– Vocabulary words will be assigned throughout the semester.

– You will be graded based on how well you complete a vocabulary word!

• Log-In Issues– If you not sure about your log-in, ask!– USER NAME = first initial and last name – PASSWORD = student id #– If you need Moodle help, there is a review session

after school on Thursday and Friday of this week ONLY!

You are required to make a weekly post summarizing what we have completed at the end of each week.

This should be a thought out reflection with no spelling mistakes that lets me know that you know what happened in class.

This is also a resource for you to use if you missed class for whatever reason.

This is a weekly participation grade!

In your seat ready to learn when the bell rings.

Prepared for class each day with all the materials that you need. Pencil/pen, paper, notebook and calculator

On-task and not disruptive. Respectful of classmates and the learning

environment.

1. Learning Goala. Transition to Unit 3: Energy & the

Hydrosphereb. Understand that there are certain physical

properties of water that influence the movement of energy in the hydrosphere.

First Law of Thermodynamics Energy can not be created or destroyed; Energy can be transferred between a system

and its’ surroundings; Energy can be accounted for in different

forms. Conservation Laws

Mass/Matter/Energy can not be created or destroyed

Forms of Energy Nuclear Radiant Thermal Chemical Mechanical

Potential Kinetic

Electrical

States of Matter Solid Liquid Gas

• Ways that energy travels– Convection– Conduction– Radiation

Efficiency Energy transfers

are never 100% complete

The “lost” energy is accounted for as “waste” heat.

H2O

It stands for 2 hydrogens (H2)

1 oxygen (O)

Water is an example of a polar molecule because, though it is not charged like an ion, its ends carry charges because of unequal electron sharing

Polar Molecule

Solid Called ice It is less dense

because it has more

volume than liquid water

It will float on liquid water

Liquid Called water Most common form of water All living things require it

Gas Called water vapor Very important to help

monitor the earth’s temp Energy is required to change

H2O from a liquid to a gas

The MOVEMENT of water molecules increases as TEMPERATURE increases. This motion breaks the COHESIVE BONDS between the molecules, and the water changes from a solid to a liquid to a gas.

Amazingly water is the only substance on Earth that can be found in all three states of matter naturally.

Liquid water is the most abundant form
